Amazon has something gadgety and motion-responsive planned for June 18

Whether or not you like surprises, Amazon seems to. The company is teasing a launch event on June 18 with a video that depicts people interacting with a product that’s never actually named or shown on-screen.

Is it the new Amazon phone the tech world has been speculating about for years? Earlier this year, reports tipped Amazon as working on a smartphone with a tilt-based motion interface, but given the video’s vagaries, the announcement could just as easily be a new 3D feature or motion-responsive interface in an upcoming Kindle Fire release. We’ll have to wait two weeks to find out definitively, though Amazon does give a few hints.

The people in the video appear to be reacting (all positively, of course) to an object or the screen of a device they’re holding in their hands, expressing surprise that whatever they’re engaged with is responding to the movements of their heads and bodies. “It moved with me,” says one of the unnamed interviewees.
